Florida Weeds Part II was written by J. R. Orsenigo, former professor of plant physiology, Agri-
cultural Research and Education Center, Belle Glade, with contributions by the following: D. S. Bur-
gis, professor of horticulture, Agricultural Research and Education Center, Bradenton; W. L. Currey,
associate professor of agronomy, Gainesville; D. W. Hall, assistant in botany, Gainesville; W. T. Scud-
der, professor of horticulture, Agricultural Research and Education Center, Sanford; T. J. Stelter,

This circular is Part II in a series developed to supplement
"Weeds of the Southern United States." It is designed to
cover more adequately weeds of specific interest to Florida
that are not represented in the regional publication. Specific
weeds included herein result from suggestions by a letter sur-
vey originating with the University of Florida Weed Science
Workshop and with county agricultural agents of the Florida
Cooperative Extension Service. Insofar as possible, botanical
and common names used in the text have been those recom-
mended by The Subcommittee on Standardization of Com-
mon and Botanical Names of Weeds as published in Weeds
19:435-476, 1971.
